Trait Implementations

impl<'env> Transaction for Txn<'env>

fn root(&self) -> Option<Db>

Load the root database, if there's one.

fn get<'a>(&'a self, db: &Db, key: &[u8], value: Option<&[u8]>) -> Option<Value<'a, Self>>

get the smallest value corresponding to a key (or to a key and a value). The return type is an iterator outputting byte slices.

fn open_db<'a>(&'a self, key: &[u8]) -> Option<Db>

Open an existing database from the root database.

fn iterate<'a, F: FnMut(&'a [u8], Value<'a, Self>) -> bool>(&'a self, db: &Db, key: &[u8], value: Option<&[u8]>, f: F)

Iterate a function, starting from the key and value arguments, until the function returns false.
